Hi, I am trying to sync my contact on with my account owner but entering the dealer number in through a vf page and passing it to a SOQL query in apex. here is my code:

Page:<apex:page standardController="Contact" extensions="DealerContactOwnerSync" >
  <apex:form >
      <tabel >
          <tr>
              <td></td><td>Enter Dealer Number:<apex:inputText value="{!dlrNum}" /></td><br/>
          </tr>
          <tr>
              <td><apex:commandButton value="Sync This Dealer" action="{!dealershipSync}"/></td>
              <td></td>
          </tr>
      </tabel>
  </apex:form>
 
</apex:page>

Controller: 

public string dlrNum; //dealer number
public String getdlrNum(){
   
        return dlrNum;
    }
   
   
    public void setdlrNam(String s) {
        dlrNum= s;
    }
   
   
   
  
  
   Public void dealershipSync(){
      
        //String branchNumber = ApexPages.currentPages.getParameters.get("branch number");

        for(Contact c : [SELECT account.OwnerId, account.Id, account.branch_number__c, account.owner.isActive, account.Active__c, account.Name, account.GMF_ACF__c, Id, OwnerId , Name FROM Contact where end_date__c = null and CreatedDate >= 2008-10-03T00:00:00Z and account.recordtypeid ='01230000000DD54AAG' and account.owner.House_Account__C = false and account.owner.isActive = true  and account.active__c = 'Y' and account.dealer_number__c =:dlrNum order by account.LastModifiedDate limit :iContactBatchSize] ){
                System.debug('Dealer Number is:***************** ' + dlrNum);
                if(c.OwnerID != c.account.OwnerID){
                    Contact mContact = new Contact();
